To all whom it may concern: I

Be it known that I, THoMAsNATHAN Rus- SELL, a citizenof the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Car Boofs,.of which the following is a specification. j I

My invention relates to car roofs ofthe outside metal type and has for an object the providing ofan outside metal roof construction that has extreme simplicity ofapplication and ready replacement of parts without mutual interference and particularly insures freedom of movement in the mutual engagement of the parts with each other and at the same time so retains the main roof-sheets on the substructure that their retaining means shall be securely applied well within the outer side-line of the car in such a way as to 'guard against their disturbance or displacement by the sidewiping accidents that may occasion serious damage and loosening of a metal roof covering; and the inventionhas for further objects such other advantages and results as may be found to obtain in the. structures hereinafter setforth and claimed.

In the accompanying drawings, forming part of this specification, and. showing for purposes of illustration a preferred embodiment of the subject-matter hereinafter claimed,

Fig. l is a top plan View. of a car roof exemplifying my invention;

Fig. 2 is a section on the line 2-2 of Fig. 1,

ig. 3 is an enlarged detail section of the ridge portion of the section shown in Fig. 2;

Fig. l is an enlarged detail section of the eaves portion of the section shown in Fig. 2;

Fig. 5 is a perspective of a portion of one of the ridge-caps showing particularly the form of its portion that overlaps the transverse joints and caps of the roof; Fig. 6 is a detail section on the line 6-'6 of Fig. 1, showing particularly .theapplicw,

tion of thetransverse joint cap and the hook strliip and the flashing at theeaves;

lg. 7 is a side elevation of the eaves 59 structure;

Fig.8 is an enlarged top plan view show ing the eaves end of the transverseijoint and p j 7 d d d i i rabbeted out alongthe top of the eaves 'por s 1. as a e? se ts! t 1 s 9-49 of Fig. .1 showing the relation of the transverse oint caps to the sides of the roof sheets;

the ridge construction showing the application of the ridge caps attheiroverlapping with each other and their intersection with the transverse joint and caps;

Fig. is an enlarged top plan View of Fig.11 is. a section similar to Fig. 2 but "J showing a modifiedfconstruction in which the roof is applied to a substructure thathas wooden "beam side-plate'sinstead of the ineltallic angle side-plates indicated in the pre- Fig. 12 is a side elevation of the roof of the same modified form to which Fig. 11 relates and i I 1 T Fig. 13 is an enlargeddetail section of the eaves portion of the same modified form of roof to which Figs. 11 and. 12 relateiand shows theconstructionv of such form at the same place illustrated in Fig. 6.

Like reference numerals indicate like parts in all ofthe drawings.=

20, 20 are the roof-sheets, each of which has an inverted U-shaped flange 21 along its ridge end, anfunder-bent hook flange 22 along itseaves-end and an'upstandinginwardly-rebent flange 28 along each of its sides. ,These roof-sheets engage'with each other in pairs bythe overlapping of their inverted U.-shaped ridge flanges along the ridge line of the roof and occupy the spaces between the transverse mullions 24 that are nailedon the top of the wooden roofsheath ing 25 at intervals along the roof, the inter: vals between the successive mullions being somewhat greater than theoverall width of the said roofesheets that occupy the spaces;

between these mullions, so that each'roof sheethas some free-space for" movement late'rally between'the' mullions on either side of it. .Each mullion isfcapped with a mul- 5 e th r tsli athifis and the es-s end of each mullion-cap is bent downward and rebent inward to cover the eaveseends of the engagement between the mullion-cap flanges and roof-sheet flanges and to hoo under and engage the said overhanging eaves-end of the mullion; The said rebent eaves-end flanges of the mullion-caps are indicated by the reference numeral 28. The mullion-caps are secured near the ridge'by the nails 29 that are driven. through the mullions, mullion-caps and roof-sheathing and into the wooden ridge-pole sections 30 that span the space from carline to c arline and are secured by the underneath ridge: plate 31 that extends under all of thecar- 1111s- The 'verla Spi dg-e flang 9-2 h? roger-seas dxt mane. ndTiiis iena cps. r h arted ei g thei'idged'ine the ridge caps, 32 that ship} lap. each other" eiid forendaiicl'ieach of v1 'eh ha iii er bi e of itsiend 'e P i tiegi shapedfas shown" in g-" iii O er the intersection of the ridge, portion of the mullion-caps and the seam formed by the overlapping ridge-flanges of the roof-sheets. The running board saddles33 rest on top of the'mullions and their caps; and .eachis see cured by a bolt 34 passing down through the runningboard saddle, ridge-cap, mullions, sh athin r d ele nd th n e n at ridgeQplate 31. Itmay be noted that the carlines' are fewer in number than the H1111? lion divided spaces along thetop of the roof and, thereiorefdo. not directly underlie the mullions, with the possible exception of the car-line at the middleof the lengthof the roof. Each carline'au is U-shaPed and exends t am" si de' e d at th a an n s cl' annelthere fis a woodenffiller 36 and'so where theccarline'underlies the mullions at the middle of the length of the car the beforegmentioned nails29c would enter the sa d wqqd' n 511a '36 (if he ee f ne a he said b,olt3l would pass through the said was filler an he tame h channe of he canine and t en threugh t nder eath ridgeepla fe 3 !.Jfistr underneath he top; 1' ad Qifleach bolt 3% a We fing n e l li v et. into a ea e lat, "reps Kaela 11m board s ddle, f p i p' e'ef fer fie l e belt i The bent aves enge 22 f the roof-sheets are loo yengaged lbythehool?

And in the form of structure shown in Figs. 11 to 13, the hook-strips aresecured by the nails 44 driven through the hook-strip and roofsheathing and into the wooden side-plate, led the fie hir e re se u ed in their epends; P rt en y the n l e dri ethrong the sidesheathing 47 and into the ee l en sid lat 45.

Fe -9 .1 t e eg in d s r pt-ie n om inspection the drawings, it willbe noted that the roof-sheets are so freely engaged along their sides and their eaves-ends that there is ample free-space for the shifting of their side flanges and eaves-flanges withn their engagingmeans, and that some freedom of movement is allowed by the simple overlapping of the inverted U flanges along the ridge ends of said sheets, although the sheets are securely retained by such overlapping ridgeeflanges and by the ridge-caps that overlie them. It will" further be noted that the retaining means along the eavesends of the roof-sheets, and such caves-ends of the sheets themselves, are secured well within the eaves-edgeof the roof, and nothing overhangs said edge except the eavesflashings that are independent of both the roof-sheets and their retaining hook-strips, so. that a siderwiping accident that may amage o r n y the e esh g will neither damage nor detach either the roof-sheets or their retaining hookwstrips. Other advent-a eswi ll be apparent from the description anc drawings. The invention, as hereinabove set forth is embodied in a particular form of construc-f ign but. may be variously embodied within he were. ifths laim here naf er ad The twenti s a e mbodied in e -m 0f eel ei e e ether an he specific term tliathaS-been shown. and described for purillustratio n and still be within the inafter made.

I e a m: y

In mullion roof for railway cars wherein such mullions define roof spacesin which separate roof sheets are confined and in which all sides of each sheet are held in such manner thatthe sheet is free for movement longitudinally of the roof, the combination of. the. mullion strips roof sheets; arranged between said mullion strips, mul-v iee; was free xiaterlee sed with the sides Q were nd ebj ie tt' ef e la ere- 1 the roof sheets, the latter being freely movable with relation thereto, the eaves ends of said inullion caps being bent downwardly and thence inwardly under the eaves ends of the mullion strips, the sheets and caps having reversely rebent flanges for such purpose which restrain vertical displacement of the sheets and caps, securing means for the ridge ends of the sheets which restrains them from movement towards the eaves but leaves them free for the said longitudinal movement paralleling the ridge axis of the roof, and securing means within the eaves lines of the roof confining the eaves ends of the sheets from upward movement and leaving them free for said longitudinal movement.

In testimony whereof, I have hereunto set my hand.

THOMAS NATHAN RUSSELL.
